In the case of a pick-up baler construction which has the usual baling unit, cross conveyer, and pick-up unit, the usual practice is to support the pick-up unit upona wheel supported axle positioned beneath the cross-conveyer. In such a case, the pick-up unit is pivoted about the axle as a center. Withthis arrangement 'a satisfac tory adjustment of the pick-up unit is somewhat diilicult because the efiective center of gravity of the unit is so far removed from the pivot axis. According to the present invention, a structure is attached to theaxle and extends away from the axle to form a support for the pick-up unit spaced from the axle, which is under the pick-up unit.

proved drive for the pick-up cylinder and conveyer of the pick-up unit.

According to the present invention, a pick-up unit is pivotally supported at a point spaced from the transverse axle of a pick-up baler by means of an X-frame construction. One member of the X-frame has an end attached to the trans verse axle and the other end attached to the baler unit frame. The other member has an end attached to the baler unit frame adjacent the tachment of the first member. A bracket member is sleeved upon the shaft and has an arm extended to a connection with the pick-up unit.

, Adjustment of the pick-up unit is had by a pivoting of the bracket member about the shaft. A ground wheel drives the pick-up cylinder at Still another object is the provision of an im- 35 by extending across the member 26. Angie members 29 attach the two members at their midsections; The free end of the member 28 is-opposite the end of the member 26 attached to the baler unit framework. This free end supports by means of a counterbalancing spring 31. 'An

one end of a shaft 30 which is supported at its other end in the bracket 21 to which the one end of the member 26 is attached; and also in a bracket 3| attached to' the baler unit framework.

'A bracket member 32 has a sleeve portion 33 journaled upon the shaft 30. An arm 34 of the bracket member extends to a pivotal connection with .a bracket 35 flxed to the underside of the pr ck-up unit l2. An arm 36 is fixed to the sleeve 33 and is connected to the baler unit framework arm 39 is also attached to the sleeve 32 and has a yielding connection with a rod Ill through.

cushioning springs ll. The rod 40 is in turn connected to an adjusting lever 42'pivoted on the baler unit framework and having 'detent mechanism 43 engageable with theftoothed portion 44 of an arcuate member 45, It will be seen that angular adjustment of the pick-up unit I2 is effected through adjustment of the lever 42 with consequent adjustment of the rod 40, the arm 35, and the bracket member 32.

With this arrangement, adjustment of the pickup unit is made about the shaft 30 as an axis rather than the axle 20. The upper end of the pick-up unit l2 rides upon a roller 41 extending the width of the pick-up unit and supported upon the cross-conveyer ll.

Drive of the cylinder I4 is effected through rotation of the wheel 22 and consequently the cylinder rotates in proportion to ground speed. A gear 49 is mounted on the axle 20 and drives a chain 50 which inturn drives a gear 5| fixed tothe end of a stub shaft 52 mounted in a hanger 53 attached to the baler unit framework. The shaft 52 is connected to a stub shaft 53 mounted in the baler unit I by means of a telescoping shaft 54 and a pair of universal joints 55 and 56. A gear 51 on the shaft53 drives a gear'58 secured to the cylinder l4.

Drive of the conveyer l6 of the pick-up unit 12 originates with a shaft 64-which may be driven by a suitable source of power, not shown. This shaft enters a gear box 65 and drives a stub shaftthrough the medium of a gear 61 which meshes with a gear 68 on the shaft 66. A gear 69 is mounted on the shaft 66 and drives a chain "which meshes with an idler gear II a gear 14 mounted on a shaft 15 at the upper end of the pick-up unit l2. 'Theshaft l drives.

ground speed of the machine. At times big bunches of hay may be picked up which tend to clog the baler and conveyers. In such cases the machine may be stopped; accordingly, pickup of material is stopped because of stopping of the pick-up roller. The pick-up conveyer continues to run, however, because it is driven from a separate source of power. The machine quickly clears itself of any clogging mass, and picking up of material is again begun.

It is to be understood that the invention is to be limited only within the terms of the appended claims.

What is claimed is:
